Nuclear theory sits at the fascinating intersection of particle physics and the forces that hold our universe together. This field explores how protons and neutrons bind inside atomic nuclei, seeking to understand the fundamental interactions that govern matter at its most dense and energetic levels. While the mathematics involved can be incredibly complex, the core questions are deeply human: how does the universe function at its smallest scales, and what happens when we push matter to its limits?
At Gist.Science, we make these cutting-edge discoveries accessible by processing every new preprint published in this category on arXiv. Our team transforms dense academic manuscripts into clear, plain-language summaries alongside detailed technical overviews, ensuring that both experts and curious readers can grasp the latest breakthroughs without getting lost in the jargon. Below are the latest papers in nuclear theory, distilled and ready for you to explore.
This paper employs a consistent folding model with a realistic density-dependent nucleon-nucleon interaction to simultaneously describe both elastic C scattering and the astrophysical factors of the radiative capture C reactions at low energies.
Using the self-consistent Skyrme Hartree-Fock in the continuum method, this study calculates the proton elastic scattering excitation function from Be to successfully reproduce and interpret the narrow near-threshold resonance in B as an single-proton state, thereby supporting recent experimental findings at the NSCL.
This study employs the Skyrme Hartree-Fock potential model to simultaneously analyze low-energy radiative capture reactions in Be()B and Li()Li, successfully describing electric dipole transitions with minimal adjustment and determining the astrophysical factor for the former reaction to be 22.3 eV b.
This paper demonstrates that the Skyrme Hartree-Fock mean-field framework, with a slight adjustment to the central potential strength, accurately explains proton elastic scattering excitation functions near the emission threshold for C, O, and O by identifying and modeling their -resonance states, including spin-splitting effects in O.
Using fully self-consistent mean-field theory, this study identifies all even-even nuclei with octupole deformation softness, attributing enhanced transition strengths to basic shell structure and predicting significant softness to quadrupole-octupole deformation.
This paper employs a spherical Skyrme-force Hartree-Fock BCS quasi-particle random phase approximation to map the landscape of nuclear deformation softness across the nuclide chart, diagnosing ground-state instabilities and calculating multipole polarizability to reveal the interplay between intrinsic nuclear shapes, shell structure, and low-lying collective dynamics.
By combining perturbative QCD equations of state with Lattice QCD data to constrain the bag parameter, this study suggests that while stable 2-flavor quark matter remains possible, stable 2+1-flavor quark matter is excluded under current theoretical assumptions.
This study combines time-of-flight measurements of beta-delayed neutron emission from Cd with large-scale shell model calculations to demonstrate that the decay is driven by a specific transition, thereby validating the model's superior predictive accuracy over global models like FRDM for -process waiting points.
This paper constructs a linear parity doublet model for octet baryons that, by incorporating the representation containing "bad" diquarks alongside the dominant representation, successfully reproduces the ground-state mass hierarchy (including the - ordering) and predicts the spectrum of excited states up to 2.5 GeV.
This paper presents a global, semi-classical framework for calculating -decay half-lives of even-even nuclei by determining the Woods-Saxon potential depth through the Bohr-Sommerfeld quantization condition, achieving accuracy comparable to experimental data while enabling efficient large-scale predictions.
